I've got a Canon EF 50mm f/1.8 II Lens and 50mm seems awful tight to me indoors. It could be that my house just isn't big enough but I'd like to check out a Sigma 30mm f/1.4 EX DC HSMfor that use.


I've got a Tamron 17-50mm f/2.8 XR Di II Lensthat I love and it stays on my XSi 99% of the time.


I will say that without a flash, even at ISO 1600,it is unlikely you'll get any real good action shots on a consistant basis indoors with any f/2.8.
